Question

I have an int that depends on users input. How do I display that int on the screen?

Here is what I have been attempting:

    <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="@int/HW"  // What goes here, This is where i am confused
    tools:context=".DisplayMessageActivity" />

Also here are my defined variables, you may have seen my post not too long ago about this program:

    // Receive messages from options page
    Intent intent = getIntent();
    int HW = intent.getIntExtra("MESSAGE_HW", 0);
    int OTW = intent.getIntExtra("MESSAGE_OTW", 0);
    int HPD = intent.getIntExtra("MESSAGE_HPD", 0);

I am trying to display the int HW on the screen, any help is greatly appreciated! Thank you!

android:text=”@int/HW” // What goes here, This is where i am confused

A default value can go there. Something that would tell you that the TextView has not been populated yet.

How do i display that int on the screen?

To display the int on the screen inside the TextView you have shown us. You need to get the TextView in your Activity with something similar to the following:

TextView textView = (TextView) this.findViewById(R.id.textViewId);

Then you can set the text on that textView with the following:

textView.setText(String.valueOf(HW));

Here is an example of adding the id to your xml:

<TextView
    android:id="@+id/textViewId"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="@int/HW"  // What goes here, This is where i am confused
    tools:context=".DisplayMessageActivity" />
